Hello, there. I'm not able to get remote desktop to work in any way, shape or form. I can only connect to the server FROM the server, which is not that helpful, but certainly a psychedelic experience to behold with its infinite reflections. I don't know what I'm doing wrong. In Settings I've enabled Sharing and Remote Desktop. I've also enabled Legacy VNC protocol. I'm trying to connect from a Linux machine to a Linux machine, which both have Zorin OS. The message I get is "Unable to connect to VNC server". Which is not very helpful. I've also tried the RDP protocol. The thing is, I've tried other remote desktop apps too and none of them work. So either I'm completely incompetent, which may very well be the case, or there's a configuration error somewhere over the rainbow causing this problem. I've also turned off the firewall on both machines. Still the same problem.
Do you have a firewall on your router? Such is the case with newer routers, that could be something. I discovered that when I upgraded mine and it had a nice big ol' firewall on it, which is fine... once I figured out it had it. In addition, is this a local machine on the same network, or on a completely different network?
You can try logging in under a different display server, Xorg, instead of the default which is Wayland. To do this, simply logout from your account so you're back at the login screen. You will see a button on the lower right with two choices:
The computers are on the same LAN. The router/modem is provided by my ISP. I presume there's some kind of firewall there, but I don't want to fiddle with that yet. I took the router out of the equation and just connected two of my computers to each other with an ethernet cable and assigned them static IP addresses. So now I had a cozy little network of two computers with no firewall, but still I get the same error message "Unable to connect to VNC server". Again, I can only connect to the server from the server. I know the computers are connected because I get a reply when I ping either of them and all the shares are available.
Tried Xorg. No change. Same error message: "Unable to connect to VNC server". Now the error message comes instantly, it's not even trying to connect. I reactivated the firewall and allowed in and out traffic on the VNC port and the RDP port. Then uninstalled the Zorin Remmina package and tried both the flatpak and the snap. No change. Same error message. So I guess I give up, or?
So with the two computers connected via ethernet, are you able to connect to each other other ways? Or is that still broken? You might need a crossover cable for that, possibly. Since you manually setup the ethernet config, you should be able to get there for something such as file transfers easily. If that doesn't work, I would then ask what you're trying to enter when connecting to each other.
The computers were definitely connected. I could ping them and transfer files in shared folders.
Now I'm back with the original setup which is a standard WLAN. One of the computers connects via wifi, the other is connected to the router with an ethernet cable. It doesn't matter if I try to connect with the IP address or the hostname. The error message is the same. Now the error message comes immediately, even after I uninstalled Remmina and purged the config files and reinstalled the original app.
Update: So the only way I can get this thing to sort of work is to be logged in at the target machine, use RDP and configure it to require no password to establish a connection. That's incredible impractical and unsafe, and NOT what I want. It means I have to physically go to the target machine and accept the request for a connection. If I configure a user name and a password, I get an authentication failure when trying to connect. The whole thing is completely absurd and useless.
So both machines are in the same location, on the same network? Remmina is for remote login. For example I had a better experience with Remmina whilst working from home to login to the works shared server with just one login, using Edge in a VM of Windows 8.1 Pro required 3 separate logins.
Maybe is worth looking into the logs to see if there's anything useful there. You can enable debugging mode from the hamburger menu, and leave that window open while trying to connect.
Yes, both machines are on the same LAN. As I wrote earlier, I connected two machines together with an ethernet cable. I did it because I wanted to troubleshoot Remmina within a very simple network. Still didn't work. Why Remmina would work in your much more complicated setup is beyond me.
Thank you for the suggestion, but I didn't really get any wiser after looking at the debugging log. Tried to connect four times. Two times RDP/VNC with password and two times without. Either I get an authentication failure error message, even though the log says it was successful, or when I try to connect without a password the connection closes immediately.
Maybe someone more observant than me can spot any useful information:

Appears you can use it on a LAN. You need to ensure that the computer you wish to connect to is a server or has server packages installed. This from Brave A.I.:
Remmina on Local LAN Use
Yes, you can use Remmina to remotely access a desktop on a local LAN. Remmina is a remote desktop client that supports various protocols, including VNC, RDP, SSH, and others. Since your query focuses on a local LAN, we’ll assume you’re looking to access a machine within the same network.
Based on the provided search results, Remmina can be used to connect to a remote desktop on a local LAN, as long as:
Both machines are connected to the same LAN: Ensure the client machine (where Remmina is installed) and the server machine (being accessed remotely) are connected to the same local network.
Port forwarding is not required: Since you’re accessing a machine within the same LAN, you won’t need to configure port forwarding on your router, as packets will be routed directly between the machines.
Remmina is installed and configured correctly: Install Remmina on the client machine and configure it to connect to the remote desktop using the desired protocol (e.g., VNC, RDP).
Additional Tips
Make sure the remote desktop service is enabled and running on the server machine.
Configure Remmina to use the correct IP address or hostname of the server machine.
You may need to adjust firewall settings on the server machine to allow incoming connections.
In summary, Remmina can be used to remotely access a desktop on a local LAN, as long as both machines are connected to the same network and Remmina is installed and configured correctly.

That must be the Captain Obvious’ cousin of AI. It’s like saying there’s no problem taking the bus to the local shopping center. You’ll get there, provided you take the bus, the bus has gas and you get off at the shopping center ...
